The Evidence Guide identifies the critical aspects, knowledge and skills to be demonstrated to confirm competence for this unit. This is an integral part of the assessment of competence and should be read in conjunction with the Range Statements

Critical aspects of evidence to be considered
Assessment must confirm the ability integrated demonstration of all elements of competency and their performance criteria, in particular the ability to
develop and implement processes to ensure regular water quality tests are conducted according to public health regulatory requirements
develop and implement processes for the use of chemicals for maintaining the correct chemical balance of pool water as governed by public health regulatory requirements
implement organisation policy and procedures
correctly anticipate pool water loadings and take appropriate corrective actio
Interdependent assessment of units
This unit must be assessed after attainment of competency in the following unit(s)

Resource implications
Physical resources - assessment of this competency requires access to
a real or simulated work environment
appropriate documentation and resources normally used in the workplace
an aquatic facility
an effectively simulated work environment or industry approved training centre
Human resources - assessment of this competency will require human resources consistent with those outlined in the Assessment Guidelines. That is, assessors (or persons within the assessment team) must
be competent in this unit but preferably be competent in the unit at the level above
be current in their knowledge and understanding of the industry through provision of evidence of professional activity in the relevant area
have attained the mandatory competency requirements for assessors under the Australian Quality Training Framework (AQTF) as specified in Standard 7.3 of the Standards for Registered Training Organisations
Consistency in performance
Competence in this unit must be assessed over a period of time in order to ensure consistency of performance over the Range Statements and contexts applicable to the work environment
Context for assessment
This unit of competency must be assessed in the context of community recreation in Australia. For valid and reliable assessment the community recreation activity should closely replicate the work environment. The environment should be safe, with the hazards, circumstances and equipment likely to be encountered in a real workplace
This unit of competence should be assessed through the observation of processes and procedures, oral and/or written questioning on required knowledge and skills and consideration of required attitudes
Where performance is not directly observed and/or is required to be demonstrated over a "period of time" and/or in a "number of locations", any evidence should be authenticated by colleagues, supervisors, clients or other appropriate persons

KEY COMPETENCIES
